Oscar Pistorius has been charged with the premeditated murder of Reeva Steenkamp
The channel reports the pictures have surfaced amid allegations officers involved in the investigation are being questioned in relation to the alleged disappearance of one of Pistorius's watches from the gated property in Pretoria.
It adds the South African Police Service refused to comment on the images.
#OscarPistorius It's believed that these pics may have been taken by an officer on the scene with cellphone - not official CSI pics. BB

Blood spatter marks on the floor and sofa are also photographed, as is a still-wrapped Valentine’s Day gift Steenkamp apparently intended to give her lover.
A card addressed to "Ozzy" - her pet name for him - sits atop the gift, accompanied by a bag of heart-shaped sweets.
Pretoria-based news reporter Barry Bateman, who has been reporting on the case has also been tweeting the images, says he believes they were taken by a police officer at the scene with a mobile phone and are not official crime scene pictures.
Pistorius denies the premeditated murder of Steenkamp and is back in court on June 4, with a trial expected to take place before the end of the year.
The double amputee claims he shot 29-year-old Steenkamp after mistaking her for an intruder.
Pistorius, 26, known as the "Blade Runner" has been on bail since shooting Steenkamp dead at his home on the morning of Valentine’s Day.
Pistorius will next appear in court on June 4
